The younger son, 15, knocked over the father. Washington Sr. got up and said, “You do that again, you ain’t gonna wake up," the complaint said. Washington went into the house and came out with a gun, pointed it at the 15-year-old and fired two or three shots, hitting him twice in the leg.

The 20-year-old son, Robert Washington Jr., was cutting the grass and ran over to the father, when another shot was fired, hitting Washington Jr. in the chest and killing him.

According to the complaint, when police took Washington Sr. into custody, he told police in the squad car, “He’s a 15-year-old kid tried bully daddy, bully me all the time.”

Robert Washington Sr. told police he had been drinking at the 15-year-old's baseball game earlier in the day and that “I should not have brought the gun out. I killed my son.”
